Lord of the Yum-Yum, aka Paul Velat, is a classically-trained organist who leads the Berkley-Hillside Presbeterian Church's choir, and teaches music at St. Pius Elementary School in Chicago, Il.

But he's so much more.

Best described as "Pee-Wee Herman and Bobby McFerrin's lovechild" by the Chicago Tribune, Velat combines guttural scat vocals, modal forms influenced by Bach fugues and a powder blue tuxedo into one of the most hilarious and oddly compelling live acts around.

Taking the human voice to a swirling trance of doo-wop and monk chant, a Lord of the Yum-Yum concert is disorienting, swirling, beautiful and strange at the same time that it doesn't take itself very seriously. His goofy demeanor belies a serious interest in improvised music, having hosted a series of concerts at Roosevelt University in Chicago called improvEXPLOSION since 2001 that help promote improvised music scene of Chicago.

Nearly inexplicable in text, Lord of the Yum-Yum has to be heard if you have ever hummed Bizet's Carmen while using the "bee-bop-a-loo-bop" vocabulary of Little Richard.
